Ammonia-acid granulation is the reaction of ammonia and acid in granulator. The acidity and basicity of granulating materials are controlled between 6.0-6.3 by the reaction of sulfuric acid and ammonia, monoammonium phosphate and ammonia. The material temperature of reaction heat reaches 75-85 and bonds with viscous and sandy materials to form granules. The pelletizing rate reaches more than 80%. The operation cost is low, the output is large, and the granules are formed. High strength, smooth and smooth without agglomeration. Compared with the same type of equipment, the production capacity is increased by more than 50%.
